spine near the postero-inferior angle of the fifth abdominal somite, 

 noticed in one of the examples previously recorded. In the latter, 

 however, the number of rostral teeth is not abnormal. 



A remarkable larval Carid found by the 'Investigator' in the 

 Mergui Archipelago almost certainly belongs to this species (text- 

 fig. 4) Although the rostral apex is broken the specimen is no 

 less than 31 mm. in length. On the carapace are two large supra- 

 orbital spines (which are absent in the adult) and the spines on 

 the lower edge of the rostrum are represented merely by fine 

 spinules. The legs are imperfectly formed, the first being chelate 

 and the second simple with unsegmented carpus; attached to the 

 first three pairs are long exopods. The hook-like projection on 

 the dorsum of the third abdominal somite, a characteristic feature 

 of adults of this species of Tozeuma, is represented by an enor- 

 mously long, flattened, outstanding process, the tip of which is 

 sickle-shaped and curved forwards. The sixth abdominal somite 

 is proportionately much longer than in adults, while the telson

exceeds the tips of the uropods and is deeply bifurcate at its apex. 

 Apart from its structure this post-larval specimen is remarkable 

 for its great size. It is probable that (as is known to be the case 

 with some other Caridea) there is an actual shrinkage in length at 

 the final moult of the larval metamorphosis ; other specimens in 

 the collection, possessing all the adult characters, are i or 2 mm. 

 shorter than the post-larval individual. 



The colouration of living individuals, as observed in the 

 Andamans, is peculiar. The specimens were deeply mottled with 

 closely aggregated dark red chromatophores, slightly paler dor- 

 sally and especially dark on the lower portion of the rostrum which 

 was fringed with bright red hairs. On the second and fifth ab- 

 dominal pleura there were large eye-spots, each being deep blue in 

 the centre, surrounded with concentric rings of black, pale yellow 

 and red, in the order named. Just beyond its middle each of the 

 inner uropods bore half a similar eye-spot, the two uropods, when 

 juxtaposed, presenting a single perfect spot when seen from below. 

 In dorsal view the spot is partially covered by the telson which is
